Although this forum is about English language does it include questions about the latin and/or greek root word questions?
Questions that ask for the etymology of an English word are acceptable, so long at you have done your research. Etymonline.com is a good place to start and can tell you the basics of where many words come from, down to PIE roots.
If you still have questions after that then you should definitely ask here, stating how your research has thrown up questions.
So, you can't ask about Latin or Ancient Greek words specifically, but only how they pertain to English.
